Since I recently got a new job in DC, I take a free shuttle bus to the Vienna Metro station. While in enroute I noticed the bus rattles and shakes a lot when it hits bumps in the road. Basically, a lot of rattles and the body shakes a lot. As as an experiment, I went the same route as the shuttle bus and to my surprise, no bumps noted. In my view a real testament to the XJ's suspension set up. It really delivers a smooth ride and good handling.
